Professor John Young, M.D., F.G.S., President, in the chair. 



Mr John J. Dalgleish, Edinburgh, was elected a life member ; 

 and Messrs. Kobert Morton, Samuel M'Culloch Morrison, James 

 White, and William Ferguson, ordinary members. 



SPECIMENS EXHIBITED. 



The President exhibited drawings and specimens of three new 

 species of Carboniferous Polyzoa, one of them being a new species 

 of Synodadia, from the limestone shales at High Blantyre, the 

 other two being species of Glanconome, from the Gillfoot shales at 

 Carluke. One of the forms of Glanconome belons-ed to a sub-senus, 

 Diplopora, which had been established by Dr Young and Mr John 

 Young, F.G-.S., for the reception of certain forms of Glanconome, 

 which have a second small pore below each cell aperture, a feature 

 which they were the first to notice in connection with Carboniferous 

 Polyzoa. Dr Young pointed out the probable use of this second 

 small pore, as allowing of the passage of processes in connection 

 with the Polyzoa, and also the affinity of this group with the 

 Brachiopoda, a subject which was of interest, and to which he 

 hoped more fully to direct the attention of the Society on a 

 future evening. 



Mr John Young, F.G.S., exhibited the test or shell of a large 

 flexible Sea Urchin, of an apparently un described species, and 

 which formed part of the large and valuable collection of natural 

 history objects recently presented to the Hunterian Museum by 

 Dr Allen Thomson. Mr Young stated that it was only of recent 

 years that sea urchins with flexible tests were known to be living 

 in our recent seas. During the cruise of H.M.S. Porcupine in the 

 North Atlantic in 1869, two specimens of flexible Echini, 

 belonging to difl'erent genera, were obtained, and were described
